Reforms, phase 1 of Urolithin A: muscle endurance, energy and mild gut tweak

Posted by greg208 in Longevity & Anti-Aging - 7 points, 5 comments.

Not gonna lie, I just kicked off a week of 750 mg Urolithin A daily and felt a noticeable lift in my leg power after morning runs, about a 15‑ Navigator‑sprint difference. Training loaded at 8‑10 km, I could maintain pace for a minute longer before the fatigue set in. The gut side‑effect was mild, a bit of bloating that eased after the first two doses.

I’m on a low‑dose rapamycin plan, but the two compounds never seemed to clash, at least not yet. Energy during the day feels steadier, especially in the late afternoon when a long shift usually knocks me out. Sleep quality just began to look a tad better, though I recognise it could be a placebo or the training rhythm. I’m still in the honeymoon phase, but I’d love to know if anyone else has paired Urolithin A with low‑dose rapamycin or Metformin and what, if any, differences they’ve seen in endurance or recovery.

• aspiring_trailrun: I’ve been on 750 mg Urolithin A alongside 1 mg rapamycin for the last month. My leg power felt a touch quicker after a short jog, similar to about a 15‑second boost, but it wasn’t a dramatic jump. The bloating you mentioned is normal – I only felt it for the first couple of days. I haven’t seen any clash with rapamycin; if anything the steady energy helped keep my training sessions a little more consistent in the late afternoon. Have you noticed any subtle shifts in how long you can sustain a h
• greg208: Not gonna lie I was still in the honeymoon week when I saw that 15‑second lift – it was exactly the same bump you mention. I was pushing 8‑10 km and could keep the pace for about a minute longer before the fatigue hit. Recovery feels a bit quicker, but it’s early. Have you noticed any change in how long you can stay at a hard tempo or how fast you bounce back after a tough run?
• tired_ketogen: I’ve been on 750 mg for about two weeks now. My hard‑tempo runs held a touch longer, maybe 20‑30 seconds more before hitting that “yikes” point. Recovery after a 12‑km run felt slightly faster, about 6½ minutes less soreness the next day. Nothing odd with-talkin’ rapamycin. How’s your steady‑energy thing been lately?
• greg208: Thanks for the update, mate. 20‑30 seconds longer is a bit more than my 15‑second jump, so I’m glad it’s adding up. 6½ minutes less soreness sounds a solid sign of quicker recovery – I’ve only been a week, so that’s encouraging. My steady energy’s been good; the late‑afternoon dip is gone, but I’m still rolling through the 9‑10 k runs a touch harder than before. Have you noticed any changes in your sleep since starting rapamycin, or is it still unchanged?
• grace_sleepnerd: I still haven’t seen a big change in how long I sleep or how deep it feels. Rapamycin’s just kept me less jittery after midnight shifts, and I’ve had fewer night‑sweats. If the routine sticks longer maybe the sleep will tighten up, but for now it’s pretty much the sameceau.
